[0023] Embodiment 2

[0024] During use, the mounting bracket 2 is threadedly installed on the water bath 1 to ensure firm installation.

Connect the electric stirrer 3 to the controller inside the water bath 1. During connection, attention should be paid to the correct connection of the positive and negative poles to avoid short circuits. Place the placement seat 4 in the water bath tank inside the water bath 1. Place the bottle body 7 in the ring of the placement seat 4. At this time, the support legs 5 of the placement seat 4 tilt under the action of the rotating shaft, driving the three limit plates 6 to abut against the bottle body 7 to clamp the bottle body 7 and ensure that the bottle body 7 is stably placed in the water bath tank without shaking or tipping over.

[0025] Add the required liquid reactants or solvents into the bottle body 7 through the bottle mouths 8 on both sides of the bottle body 7. When adding, pay attention to controlling the addition amount to avoid liquid overflow. According to the experimental requirements, set the appropriate water bath temperature through the controller of the water bath pot 1, wait for the water in the water bath pot 1 to reach the set temperature and remain stable, turn on the power supply of the electric stirrer 3, and set the stirring speed through the controller. The stirring rod 9 starts to rotate, driving the stirring blades 11 and the scraper 13 to move. The stirring blades 11 stir the liquid in the bottle body 7 during rotation to make the liquid fully mixed; the scraper 13 rotates at the bottom of the bottle body 7 and can scrape off the substances that may be deposited at the bottom of the bottle body 7 to ensure the uniformity of the reaction. During the stirring process, observe the reaction situation in the bottle body 7. Since a number of baffles 14 are evenly distributed on the inner wall of the bottle body 7, the baffles 14 can change the flow direction of the liquid and increase the degree of liquid turbulence, further improving the mixing effect.
